How to seal a driveway and fix cracks


Are your asphalt driveways showing the true beauty and value of your home? Cracked driveways are dangerous and will get worse over time. A stained driveway that is faded or stained can be a eyesore and devalue your home’s worth.

You can seal your driveway with materials and tools you find at your local home centre.

Crack sealing basics for driveways and roads

This is not the hot-tar asphalt that professional companies install. This is a more complicated and expensive process that involves several layers of heated asphalt being laid and then smoothed with a roller. It is not the tar-and chip method. Hot asphalt is spread on the driveway and then a layer of angular stones is applied. The top is then rolled.

This is a minor, do-it-yourself asphalt driveway patching and surface sealing job. This cold method uses unheated, ambient temperature substances to fill cracks and holes. The entire driveway is covered with an unheated sealant after the patching.

Before You Begin

Your driveway will appear new and smooth after completion, especially from a distance. The cracks and holes will be clearly visible under the sealant if you look closely. The sealant will appear slightly shiny.

This project can be completed by anyone who is able to lift 50 pounds and in good physical condition. A 5-gallon bucket with driveway sealer covers approximately 350 square feet. Do not apply sealer during extreme heat or cold seasons. Instead, try to maintain moderate temperatures between 65-90 degrees Fahrenheit.

What you’ll need

Equipment / Tools

  • Pressure washer
  • Wire brushes
  • Stiff broom
  • Old screwdriver
  • Squeegee


  • Asphalt cleaners, such as Latexite Driveway Cleaner/Degreaser Prowash
  • Oil cleaners, such as Latexite Oil Spot Primer
  • Flexmaster Crack Sealer is an asphalt crack filler
  • Road Rescue Asphalt Patch is a cold asphalt patch
  • Rust-oleum EpoxyBlacktop Coating is a driveway sealant


Get rid of all debris

Remove weeds from cracks by hand or using a string trimmer. To remove dirt and rocks, use a trowel or a screwdriver. Reduce the amount of dirt and gravel that is in cracks to ensure they don’t protrude above the surface.

Clean the Surface

You can clean stubborn stains from your driveway with an oil cleaner.

Use the asphalt cleaner and then pressure wash the surface. Allow the driveway to dry completely. A good cleaning will ensure that the asphalt sealant adheres better to your driveway, as it does with other projects.

Fill in the Large Holes

Use the cold asphalt patch if you have large holes to fill. The dense material can be poured straight from the bag without heating. Curing times can vary so make sure to check the bag for specific instructions.

Seal the Cracks

Apply asphalt crack sealer to cracks. Elastomeric sealers are rubberized and expand and contract with your driveway.

Apply the First Coat of Sealant

Use the squeegee and spread the asphalt sealer parallel to the house to seal the driveway. The sealant should be allowed to dry as per the product instructions.

Apply the Second Coat of Sealant

Once the first coat is dry, seal the driveway with the squeegee. Make several passes perpendicularly to the house using the asphalt sealer. This second coat should be dried according to the product instructions.

You will generally need to wait for up to 48 hours before you can drive a vehicle on the sealed driveway.

Tips to Seal a Driveway

  • Ripples and bumps will not be treated with asphalt driveway sealing. Sealing a driveway is putting down a thin layer liquid sealant. This conforms to bumps and ripples, and is not the same as asphalt paving.
  • Make sure all water is removed from the surface when pressure washing. If you don’t, debris could remain on your driveway.
  • Hot-applied crack-filler, such as Latexite PliStix, may be purchased. This requires the use of a torch and butane. Although hot-applied crack filler has a longer shelf life than cold-applied products, it can be more difficult and time-consuming to apply.
  • You can achieve a smooth finish without brush strokes by using the checkerboard technique. Be careful not to alter this. The term “checkerboard” is used to describe the process. However, the result will not look like a checkerboard pattern if it’s done correctly.
